I I. Application filed February 5, 1921. Serial 1T0. 442,638..

acter whose lens ring or holder is entirely within the open end of thelamp body.

This invention consists in a cup-shaped body having its edge turned inwardly and then rearwardly to constitute. a substan'-' tially fitting within this re-entrant cylindrical fiangeon the body.

It also consists in a body and a lens holder of this. character provided .with inclined members which interlock to secure the lens holder in position when the lens "holder is pressed in or recessed portions 24, Figs. 6

rotated within. the body.

' It further consists in the details ofconstruction illustrated in the accompanying drawing and particularly pointed out in the;

claims.

, In the drawing, tral section of the front edge of the body and of the lens holder mounted thereon. Fig. 2 is a front elevation of this lamp with the lens holder removed. Fig. 3 is a similar view of the body alone. Figs. 4 and 5 are sections on the'lines'44 and 5- 5: of Fig. 3. Fig. 6 is a side elevation of a portion of the lens holder. Fig. 7 is an inside elevation of a portion of the lens holden. Fig. 8 is a section on the line 8'8 of Fig. 7.

Similar reference characters refer to like parts throughout the several views. 7 'In the large majority of headlights, the lens holder fits around the outside of the edge of the cup-shaped body, and, when the I lamp is damaged, it is often impossible to remove the lens holder. The present lens holder is entirely within the re-entrant end of the lamp body and it requires practically entire destruction :of the lamp toprevent the lens holder being removed Furthermore, the present construction is of dis-' of the lens in still farther and turned until-the in-' tinctive and'very pleasing appearance.

The lamp body 1 is formed with a'cylindri cal 2;: 2, a radial flange 3, a cylindrical cylindrical flange, and a lens holder portion 19 and an inwardly and rearwardly Fig. lis a ve1'tical cenflange 4, and asecond radial flange 5 which pre erably terminates in a curved lip 6. T ese parts 2 to6 inclusive constitute the re-entrant end of the body. While thisstructure mig t be formed from a single piece of sheet metal, I refer to form it of two-parts joined by 'wel ing or brazing at the outer or nner edges of the radial flange 3. The sec- -ond radlal flange 5 may be formed with holes 7 to receive the small tongues 8 on the archedsprings '9. Y

A reflector, 12 within the 'body nhas a radial extension 13 provided with a groove to receive the packing ringv 15, a cylindrical flange 16 and a radial flange 17 which fits slidably within the cylindrical flange 41of the body and contacts with the springs 9.' The lens .holder' consists .of a cylindrical inclined portion 20 whose inner edge'contacts with the lens 22. Small fingers .23 may be struck up from the cylindrical portion 19 to hold the lens in positions The cylindrical portion 19 v is formedv with and i7, concentric with the main portion 19, and from-these portions '24 the outwardly extending locking members A shown inFig. 6 are struck up, and consist of the inclined 1 portions 25 and the shoulders 26. I

flange 4 of the body are ribs or flanges B consisting of inclined portions 27, rounded shoulders 28 and straight-portions 29, and adjacent thereto are the small tongues 30 which serve as stops for the locking members on the lens holder. These recessed portions 24-, on the lens holder are set back sufliciently to permit the locking ribs and stops on the flange 4 of the-body to pass in freely.

' The flange 17 of the reflector is-cut away at 31, Fig. 2, to permit these ribs and stops on packing 15, the ribs B and'stops- 8B Extending inwardly from the cylindrical the cylindrical portion 19, guides the 30 beingwlthinythe depressed portions 24 holder. The'lens holder is pushed "on the reflector, the packing presses the springs will prevent reverse rotation oi the lens holder in the body and the small stops 30 will limit the rotation in that di rection. The springs 9 resting on the flange 5 of the body press against the flange 17 against the lens, the lens presses against the part 20 of the lens holder, and the locking members A on the lens holder press out against the ribs B on the body so that rat tllng is prevented at all points,

The particular conformation of the for:

ward end of the lamp body hasnothing to do with the present invention and may be changed as desired so long as an opening is provided to receive the lens holder of such size and shape that the lens holder is freely slidable 1 in such opening. I prefer to so form the end of the body and the lens holder that when the parts 32 are assembled the radial flange 3 and the adjacent part ofthe lens holder will be substantially in the same 5 I i i the opening and a cylindrical flange extendplane. I

It is evident that the construction of the locking devices for retaining the lens holder 'in position may also bemodifled to suit the ideas of those skilled in the art without departing from the spirit of my invention as yll claim 1. in a headlight, a sheet metal body having an opening and the metal of the body around the opening being bent radially inwardly and then rearwardly to constitute an interior cylindrical flange, a lens holder rotatably mounted within the opening in the body and embodying a portion extending within said cylindrical flange, and means between the lens holder and the cylindrical flange to secure the lens holder in position so that its outer portion will be practically in the plane of the radial end of the lamp body.

2. In a headlight, a sheet metal body having an opening and the metal of the body around the opening being curved inaeeaaae wardly to constitute an interior cylindrical flange, a lens holder rotatably mounted within the opening in-the body, and means tosecure the lens holder in position, comprising inclined engaging members attached and to the cylindrical in-the plane of the radial portion of the body,

and means to secure the lens holder in position.

4. In a headlight, a. body having a cylindrical opening and a cylindrical flange surrounding the opening, locking ribs extenda ing inwardly from said flange, a lens holder having a cylindrical body provided with receases to receive the locking ribs on the vbody and locking members extending'outwardly in said recesses and adapted to engage the ribs on the body-to secure the lens holder in the body. 7

5. In a headlight, a body having an opening, a radial internally extending flange at ing rearwardly from the inner edge of the radial flange, both flanges being integral with the body, a lens holder rotatable within the cylindrical flange and having its outer edge in the plane of said radial flange on the a body, and means to secure the lens holder in the body;

6; In a headlight, a bodyhaving an open-- on both the lens holder and the cylindrical flange of the body, said engaging members having inclined engaging. surfaces and rounded shoulders to prevent return movement of the lens holder.
